Brainbot, the artificial intelligence, seems to have got tired and gone on holiday. Instead of solving problems, it now sends jokes; instead of searching for information, it sends photos of cats; and sometimes it even asks for advice.
🦊 Pif the Fox, 👴 Grandfather Pythagoras and Tesi are already trying to sort everything out, but they cannot do it without the participants. Only by completing all the modules and restoring order to Brainbot’s thinking can they bring it back to normal.

Logic Module
Brainbot is trying to prove to Pif that cats are actually dogs because they all have tails. 🦊 Pif: “Well, I have a tail too!” Solve the task to fix Brainbot’s logic.
Brainbot suggests taking a pizza break.
First, Pif the Fox eats one sixth of the pizza.
Then, Grandfather Pythagoras joins him. After that, Pif eats 7 more slices.
In total, the numbers of slices eaten by Pif and Grandfather Pythagoras are in the ratio 2:3. How many slices was the pizza originally cut into?
Enter a number.

Fast Response Module ⚡️
Brainbot answers faster than it thinks — and makes lots of mistakes.
Tesi: “At least it’s fast!” Give the correct answer and show Tesi that accuracy matters more than speed.

Memory Module
The conditions of the problems keep changing.
👴 Grandfather Pythagoras: “We must restore Brainbot’s memory urgently!”

Replace each letter with a digit so that the multiplication is correct:
ABVGD × 4 = VGDBA
The same letters represent the same digits.
Different letters represent different digits.
Enter the number ABVGD.
ABVGD × 4 = VGDBA
The same letters represent the same digits.
Different letters represent different digits.
Enter the number ABVGD.
